Gifting Exploit!

So, my friend decided he wanted to gift me Vi, but he noticed the restriction of not being on my friendslist for two weeks or more. So we sought out for a way around this, and he thought "Well, why don't we just use the endgame screen to gift it to you?" And I thought that was a genius idea. Sure enough, we finish the game, and at the final scoreboard, he sends me the champion and it goes through fine. This was something that happened a few months ago, but I forgot to report it. It's practically a super easy way around the friendslist idea, and I wanted to let Rito know so they can do something to patch it. Or completely ignore it now, considering you only have to wait one day before you can gift someone now. xD
